USB drive and port number question

[rick11]

I need know when a drive is a USB drive, what USB port is it in?
For the system I am doing this on, I do not have to worry about
hubs plugged into hubs (into hubs...).
It's just the motherboard with 3 USB ports in it.
I know it just has 3 USB ports because the whole thing sits on a table
without any case around it.
Can I tell which drive is in which port?
And if so, how?

BTW: drives may or may not be there at boot, different thumb drives may
get shoved in at any time (so having a known list to recognize from is not viable),
and drives may get yanked without much warning (fixing disks not quite written to completely is a separate problem).

This may be a script question and/or a USB question
and/or a C# question.
Apologies in advance if this is the wrong place to post it,
but I am using C# to make a WQL query to get drive info.

I have a C# script that gets the drives out of my local system
(using Win32_LogicalDr ive).

I have already figured out how to remap drive letters that bump into
one another between reboots. I understand the simple method I am
using won't work for the C drive (but I don't want or allow it to) and not for
drives with multiple partitions on them (which is not a problem for me here).

Here is my script so far:

Have you tried checking the name of the drive through windows explorer, or have misunderstood your question.

I'm looking to do this programatically from C#.
How do I get a USB hub / port number from a Win32_LogicalDr ive?

I found a sample script at this site for how to get the Win32_DiskDrive
from the Win32_LogicalDr ive.

But I am still at a loss for how to get either of those to a USB hub and/or port
number.
